Sympathetic stimulation results in renin secretion by the kidneys and causes a relaxation of the bladder. Accompanied by a constriction of the bladder sphincter, sympathetic stimulation tends to decrease urination and promote fluid retention.

Stimulation of the sympathetic nervous system causes the kidneys to constrict blood vessels, reducing blood flow to the kidneys. This can lead to a decrease in urine production and help conserve body fluids in times of stress or emergency. Additionally, the sympathetic nervous system can stimulate the release of renin, an enzyme involved in blood pressure regulation.
with stimulation of the sympathetic nervous system there will be a. constriction of the pupils b. dilation of the coronary arteries c. constriction of selected blood vessels d. profuse sweating
Heart muscles has there own rhythm of contraction. The sinoatrial node has the fastest rate of contraction. That is why it governs the rhythm of the heart. You have the control of the autonomic nervous system over the heart rate. Stimulation of the sympathetic nervous system increase the heart rate. Stimulation of the parasympathetic nervous system decrease the heart rate.
Sympathetic postganglionic fibers end in effector organs such as smooth muscles, cardiac muscles, and glands. They innervate these structures to modulate their activity in response to stress or stimulation of the sympathetic nervous system.
With current technology it is not yet possible to simulate a sympathetic nervous system
The abbreviation for the Central Nervous System = CNS.
